METHOD FOR MAKING MACHINE-FOOTED GLASSWARE.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed October 4, 1907. Serial No. 395,825.

blow-hole of the mold 1, and the blank fication, reference being had therein to the accompauv ing drawing.

This invention relates to a method of making machine footed glass-ware, and its object is to provide a method whereby a pressed glass articl may be footed or provided with a supporting foot or base during the Pl'Ot'Lh'A of immufaeture.

The formation of stems and feet upon glass-ware is both laborious and expensive. and the present invention aims to materially simplify the method of footing glass articles, thereby reducing the cost and lessening the tin: and labor in performing the work.

The method will be specifically described hereinafter, in connection with the accompanying drawing which forms a part of this specification, and its features of novelty will be set forth in the appended claims.

In the drawing:--l*igure 1 is a sectional view of a mold containing a pressed blank;

Fig. 2 is a similar view illustrating the pressed blank having been blown to form the body of the vessel and blown onto the foot of the vessel. and Fig. 3 is a side elevzr tion of the completed article removed from the mold.

The reference numeral 1 designates a mold to receive a blank 2. I prefer to use a mold of the type disclosed in Letters Patent .\'o.

glass articles.

The foot 3 is formed in any suitable mold following steps to-wit: The pressed blank 2 is formed within a mold, and the foot 3 is simultaneously formed in its mold, after which the foot is removed from its mold,

and placed upon a removable bottom-plate 4.

The pressed bank is then positioned within the mold in which the body of the article is to be formed, and suitably supported until Hm mold is closed; the temporary support which is recognized in i the art as the basic patent; on machine made 5 for the pressed blank is then withdrawn from the mold, the foot 3 is placed in position and the blow-head 5 lowered into the pressed then blown to form the body of the article and at the same time allix the same to the foot 3.

The distinguishing characteristic of the present invention, 1.; that the pressed blank 2 is not removed from its mold, no warm-- ing in of said blank being required.

While the improved method is not restrict'cd to the employment of any specific form of mold, I preferably employ the mold shown in l igs-l and 2, consisting of the hinged mold sections (3 and 7 re ating upon a supporting plate 8 formed with a central opening 9 of sullicient diameter to permit the mold support to pass through it. The plate 8 is supported by standards 10 upon a base 11, and is formed at one side with a triangular slot 12 through which the foot 3 is inserted.

Above the plate 8 rests a sectional base plate 123 secured by the pivot pin 14 of the mold, and provided with a handle 15 to facilitate the required opening and closing movement of said nx ld plate Ill. The plate 1 is al o formed with a central opening It} fitting the upper end IT of the foot.

A horizontal movable frame 18 is supported upon the base 11, said frame being of rectangular spider form, and provided on opposite sides with inclined cleats ltl the spaces between which constitute guide-ways 20 to receive arms 21 projecting horizontally from a rod UL). the upper end of which is adapted to extend up into the mold 1, and carries a suppor 23 to receive the pressed lank 2.

In carrying out my improved method, the pressed blank 2 is placed in 'the support 33,

, and the mold l is then closed so as to supand the nnproved method consists of the? port the presed blank 2 from the neck thereof. The frame 18 is then moved longitudinally so as to withdraw the rod 22 and the support from the mold, leaving the pressed blank supported by the neck thereof in the mold 1. The foot 3 is then placed in position and the sections of the plate 13 closed as shown in Fig. 2, after which the blow-head 5 is lowered into position as shown in Fig. 1 and the blank is then blown so as to form the bocly 2 asel-iown in Fig. *2, and at the time of time blowing the body, the same is caused to adhere to the foot 3, completing the article The mold l and the sections of the plute13 are then opened, antlthe finished article removed.

Having fully described my invention What I claim new and desire to secure by Lettors Patent is,

1. The herein described method o'finak ing footed or stemmed glass articles, which oonsists in forming a blank Within a mold; forming the foot or stem in separate molrl. then suspending the blank in a mold with the foot or stem eentei'etl beneath the blank, and finally blowing the bleak in the molcl to form the body of the vessel and at the some time blowing it onto the foot or stem.

2. The herein described method of making footed or stemmed glass articles, consisting in forming a blank within a mold, suspending tlie blank in a mold, positioning a foot or stem beneath the bltltlli and then blowing tlie blank in the mold to form the body of the vessel simultaneously blowing said body onto the foot or stem.

in test non" whereof I alfix'my signature in the m once of two witnesses.
